Scalenut combines an AI writer with SEO optimization in a single tool. It includes real-time SEO scoring and a one-click “Fix It” workflow to optimize drafts. But it is a retrofitted search tool, scored against the Google SERP, with no view into how AI answer engines describe your brand.

WriteWorks is built for AI search from the ground up. It measures how 8 AI engines answer your buyers, ChatGPT, Claude, Gemini, Perplexity, Meta AI, Microsoft Copilot, Google AI Overviews, and Google AI Mode, across 23+ regions and buyer personas, tracking citation rate, share of voice, and sentiment. Then it engineers the content that wins the citation, scoring every draft against three AI-visibility lenses, and proves the lift.

Track it. Engineer it. Win it. Prove it. Scalenut grades a page for one search surface; WriteWorks closes the loop across all 8 AI engines.
